摘要: A nonlinear frequency response analysis of a smart functionally graded plate operating under heated substrate surface is presented. The mainly for investigating the effect temperature on harmonically exited vibration characteristics plates and also corresponding control authority piezoelectric fiber–reinforced composite actuator bonded to surface. negative velocity feedback strategy utilized so as achieve damping. temperature-dependent material properties ceramic metal–based are in thickness direction. Based von Karman strain–displacement relations assuming periodic motion, dynamic incremental finite element model overall developed. An arc-length extrapolation technique with new determining arc length used numerical solutions. rev...
